CORRECTION DEVICE FOR TALKING-MACHINES;

A Specicationiof Letters Iatent.

aplicaran mea :rune 29, 1917. serial No.`177,621.

To all whom t may concern Be it known that I, SAMUEL SHELLY, a citizen of'the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Correction Devices for Talking-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form-a part of this specification.

My invention relates to talking machines of the character used for dictation purposes and has for its special object the provision of simplified means for imparting information to the transcriber. Devicesadapted to this purpose are known in the art. Thus it is known toprovide a rotary disk operable by the traveling sound box to turn on its axis once during the travel of the sound box frompone end to the other of the cylindrical record. This disk is provided with a scale and other characters, upon which, at any given point, a mark may be made which, by reference to the scale and the particular other character registering with the mark,

.will inform the transcriber that, at a corresponding point in the length of the record, something special-must be done; for example, that a mistake has been made, or

. that a particular communication should be rushed, or that a certain number of carbon c'oples should be prepared.

My invention constitutes an improvement `upon this type of correction and information device. One objection to the known .devices is that their construction is more or less complicated. One ofthe objects of my invention is to simplify the construction so as to render the use of the vdevice commercially practicable.

racy due to slight diferences between the machine used for dictation and the machine used for transcribing. Ordinarily, as is well known, records are transcribed from a different machine from that upon which they are dictated. The two machines, except in minor features, are essential duplicates. After a record is made on the first machine it is removed from the cylindrical holder thereof and slipped onto the cylindrical holder of the second machine, the indicator disk being also transferred from one machine to the other.

Another and` serious objectionto the known devlces is then' lack of accu' Due to the lack of ex- 'ratented May 14, 191s. l

act correspondence in the dimensions of the two holders (which are tapered to facilitate the application of the'record) or due'toa failure on thepart either of the dictator or transcriber to slip the record onto its holder to precisely the same extent, the indicator registers falsely, which is a source o f confusion and error. One of the important objects of my invention is to obviate this diii'- culty. Another objection to the known device is that special disks (.or in another type of dictating machine, special. strips) must be provided, which adds to the equipment required. To avoid this, another object of my invention is to so construct the machineas to enable the cover of the box containing the record to be utilized as the indicator, thus dispensing entirely with the necessity of adding anything to the equipment required for operatlng machines devoid `of any correction or mformatlon devlce.

In describing a preferred embodiment of my invention, I shall show how it is applied i to a well known type of machine and will describe only such parts of the latter as more directly coperate with my improved attachment. In the drawings, which .illus.

trate such a preferred embodiment;-

-Figure l is a front view of a portion of l a talking machine embodying my invention.

- Fig. 2 is a partial top view of same.

Fig. 3 is a cross sectional view on line 3 3 of Fig. 1.

Fig. 4 is a section like Fig. 3 showing 2 parts in another position. f Fig. 5 's a detail face view of the indicator.

Fig. 6 is a sectional view showing means by which the sound box is moved.

The body of the. machine a carries the usual u per-works mounted on the standards;y

or brac etsb. These consist primarily of the tapered. record holder c supported in the bearing d and rotated by meanseof the pulley e, and ofthe sound box f slidable upon the bar g.` I have shown the usual ejector handle L and the transmitter hook switch z'. A'pointcr 7' depends from the sound boX f to give the eye of the operator the position of the needle ofthe instrument longitudinally of the record lc. A

The sound box f is moved, by old and well known means, along bar g from left to right,

beginning with the needle and pointer jin the rst turn w of the Spiral groove in the' record and continuing until they run past the last turn y thereof. Pulley e, by means of gear train 7, rotates the feed screw 8 for moving the sound box. The feed screw turns centrally inthe stationary bar g, along the bottom of which runs a slot 9, A plunger 10 is mounted in the sound box carriage and is spring-pressed up through slot 9 against the feed screw. The top end of this plunger contains thread portions which mesh with the threads onpthe feed screw, thus acting as a nut to move the parts carrying the sound boX along bar g. when the feed screw is turned. By moving lever l the needle of the instrument is raised from the record and the sound box f disconnected from its driving means, so as to be readily slidable by hand along bar g. An arm s projects downward from the sound'box f, and slides along a rod t, parallel to bar g. This serves to maintain the sound box in an upright position and prevents its turning about bar g.

Thus far nothing new has been described, but merely the well known parts of a certain form of phonograph used for dictatingpurposes. The object of my invention is to locate any desired points in the record groove between the points and y, a longitudinal distance of approximately 5 inches, and consisting of many hundreds of turns of the spiral groove.

The sound box f has the sleeve extension m, upon which is mounted a bracket n for carrying my indicator device. This consists of a holder 0 upon a stud p projecting from bracket n. The hub of holder 0 also carries a gear wheel g meshing with teeth r cut upon the upper side of bar g. The sleeve Ysa m is cut away to allow gear g to get into mesh with the teeth r.

Thus the movement of the sound box along bar g turns gear g, and therewith holder 0. Moreover, gear g is of such diameter as to turn one complete revolution in the before mentioned length of travel of 5% inches of the standard records, the indicator holder o therefore doing likewise.

Upon thisholder is placed an indicator u Y which, as before stated, is, or may be, the cover of the box containing the record. That is, it is of circular form with a iange or rim on the general cap-shape of the box cover. This indicator is slipped over the holder 0, a springfr in the rim of the latter holding the indicator from inadvertently turning thereon after being set.

A pointer lw, extending in front of the indicator, is pivoted below to an extension from bracket p, and carries a tail w whereby it may be opened and closed as 4shown in Figs. 3 and 4. When an indicator is slipped on the holder, as shown in Fig. 3. its rimor flange strikes and pushes tail w backward, bringing pointer w up in front of the indicator inits active position. Preferably a spring z is arranged to snap the pointerA 'w beyond the position to which it is pushed by the flanged rim of thel indicator, so that the pointer will be against eating position and the pointer will remain in the position shown in Fig. et; although, if desired, the pointer may be moved by hand slightly toward its closed position, the spring then completing its return to the position shown in Fig. 4.

The circular face of the indicator carries .a scale on its edge corresponding to the 51g inches length of record, and within this are concentric annular rings (see Fig. 5) upon which can be made marks, as before described, calling attention to the particular sections of the record corresponding to the positions of the marks upon the above mentioned scale.

rlhe indicator is placed upon the holder 0 so that a certain point on its periphery, marked zero, is directly in line with pointer a when the needle and pointer j are in the iirst turn of the record groove. Thereafter, as the needle moves along and the indicator u turns, the marks are made thereon in the proper 'annular space always in' line with pointer fw.

When the record is to be read oil', the

indicator is placed upon the holder of the j transcribing machine, in the same way: with ,slot u registering with the end v of hand until it does so, making the correction easily, and insuring that 'the scale upon the indicator corresponds withv the record, the same on the transcribing machine as on the machine it was made on.

To insure that the pointer shall register accurately with zero on the indicator when the latter is applied to its holder on the dictating machine, without any special effort being made by the user to eect the alinement, the flange of the indicator is notched at u. After the indicator is applied to the holder it is turned thereon until the notched part of the indicatorv engages the slightly projecting end v of the spring o. The notch is so positioned that in this position of the indicator the pointer accurately registers with zero.` On the transcribing machine, however, the edge of spring does not project so as to engage the notch, and there Ais nothing to -prevent the indicator being turned, as herembefore described, to efect the alinement of the pointer with zero.'
